Let the wealth flee...

One of the biggest arguments against a progressive system of taxation and regulation is that the rich flee with their wealth to places more accommodating to its growth.

This otherwise legitimate fear can be powerfully allayed with a recognition that the wealth they cannot take are only those with fundamental use to human progress: the land.
As the rich e-transfer zeroes to the left of the decimal in their accounts the poor of a nation have no similar option to migrating digital wealth they don't possess, but the radical quality of digital wealth is that it doesn't really exist!

So let the wealth flee, but damn them when they come for the land.
